math 8th please help
posted by megan on .
a teaher chooses a student at random from a class of 10 boys and 15 girls. Find the odds favor of and for the odds against each event.
1. choosing a girl
2. choosing a boy
i don't understand what the odds of something would be
First, find the total amount of students in the class. 10+15=25.
There are 10 girls so the odds of choosing a girl are 10/25, reduced to be 2/5
There are 15 boys so the odds of choosing a boy are 15/25, reduced to be 3/5
The answers are
1. 2/5, or 2 out of 5
2. 3/5, or 3 out of 5
i thought that was probability...... sorry i must have messed up big time on my homework then
It is strange that i am in 7th grade and I know this and you do not....
Choosing a girl at random is more likely to happen because there are 5 more girls than boys.
